Le produit métal lique de type bande en défilement est alors plonqé dans le dit bain au niveau de sa surface de métal liquide, passe sur un rouleau de fond dans le bain puis passe entre des rouleaux correcteurs afin de ressortir du bain qénéralement verticale ment à la surface du bain afin de transiter dans un système d'essoraqe disposé en sortie du produit hors du dit bac et dédié à essorer chaque face du produit de type bande, par exemple sous forme de deux lames d'air disposées transversa lement (direction horizontale) de part et d'autre de la bande en vis-à-vis de chacune de ses faces. Usuellement, une tra verse de maintien du système d'essoraqe est disposée à une première hauteur de la surface haute du revêtement liquide dans le bac. Cette traverse se compose au plus simple de deux poutres pouvant être disposée au-dessus, à côté ou sous cha cune des deux lames d'air afin de les maintenir à une dis tance souhaitée et de part et d'autre des faces de la bande lors de l'essorage. Ces poutres sont solidarisées à la péri phérie du bac et sont amovibles afin de pouvoir écarter le système d'essorage complet par exemple lors d'une opération de maintenance ou de changement de bande. Mainly, the coating is provided in a tank forming a coating bath in the form of liquid metal, for example consisting of zinc, maqnesium, aluminum or other elements to form specific alloys. The moving strip-type metal product is then plunged into said bath at the level of its liquid metal surface, passes over a bottom roll in the bath and then passes between correcting rollers in order to emerge from the bath generally vertically at the bottom. surface of the bath in order to pass through a squeezing system disposed at the outlet of the product outside said tank and dedicated to squeezing each side of the strip-type product, for example in the form of two air knives arranged transversely (horizontal direction) on either side of the strip facing each of its faces. Usually, a retaining rail for the dewatering system is arranged at a first height of the upper surface of the liquid coating in the tank. This crosspiece is made up of two beams which can be placed above, next to or under each of the two air spaces in order to keep them at a desired distance and on either side of the faces of the strip. when spinning. These beams are secured to the periphery of the tank and are removable in order to be able to separate the complete dewatering system, for example during a maintenance operation or when changing the belt.
En aval du système d'essorage, il est aussi possible de dis poser un dispositif, tel qu'un dispositif de stabilisation du produit métallique revêtu, afin de garantir un maintien plus stable et précis dudit produit entre les deux lames d'air. A cet effet, ce dispositif de stabilisation peut être maintenu de diverses manières, comme par exemple : Downstream of the wiping system, it is also possible to arrange a device, such as a device for stabilizing the coated metal product, in order to guarantee a more stable and precise maintenance of said product between the two air knives. To this end, this stabilization device can be maintained in various ways, such as for example:
- W02006006911A1 (délivré sous EP1784520B2) prévoit que le système d'essorage est solidarisé à la traverse et que le dispositif de stabilisation est agencé dans la tra verse et présente une connexion fixe au système d'essorage . - WO2006006911A1 (issued under EP1784520B2) provides that the spinning system is secured to the cross member and that the stabilization device is arranged in the cross and has a fixed connection to the spinning system.
- W02017036703A1 prévoit que : - W02017036703A1 provides that:
- le système de soufflage est suspendu à la traverse ;- the blowing system is suspended from the cross member;
- le dispositif de stabilisation est d'une part disposé entre la traverse et le système d'essorage et d'autre part le dit dispositif de stabilisation est suspendu à la traverse par un moyen de maintien à la traverse indé pendant du système d'essorage. - the stabilization device is on the one hand arranged between the cross member and the wringing system and on the other hand said stabilization device is suspended from the cross member by a means of holding the cross member independent of the wringing system .
- US2017009326A1 (fig. 15) prévoit enfin que le système d'essorage est suspendu à la traverse et le dispositif de stabilisation (comprenant des électroaimants mobiles) est disposé en sandwich entre le système d'essorage et la traverse. - US2017009326A1 (fig. 15) finally provides that the wiping system is suspended from the cross member and the stabilization device (comprising mobile electromagnets) is sandwiched between the wiping system and the cross member.
D'autres dispositifs autres qu'un dispositif de stabilisation sont aussi prévues dans ce type d'installation de revêtement, par exemple un dispositif comprenant des capteurs de dis tances disposés sur le système d'essorage, le dispositif de stabilisation ou la traverse, les dits capteurs permettant de mesurer une position horizontale de la bande en défilement par rapport à une position de référence. Toutes ces configurations d'installation de revêtement pré sentent ainsi des géométries très statiques, et dimensionnées pour des types de produits et de revêtements classiques. Or, les technologies de revêtements évoluant avec le temps, il est de plus en plus demandé de pouvoir adapter dynamiquement la géométrie de ces configurations d'installation de revête ment. Other devices other than a stabilization device are also provided in this type of coating installation, for example a device comprising distance sensors arranged on the wiping system, the stabilization device or the cross member, the said sensors making it possible to measure a horizontal position of the moving strip with respect to a reference position. All these coating installation configurations thus present very static geometries, and dimensioned for conventional types of products and coatings. However, as coating technologies evolve over time, it is increasingly required to be able to dynamically adapt the geometry of these coating installation configurations.
En effet, en fonction des propriétés mécaniques et chimiques du produit à revêtir, du revêtement employé, du procédé de revêtement et des tolérances de qualité de revêtement à ga rantir par des mesures spécifiques (distance de bande, épais seur de revêtement, composition de revêtement, température, pression, analyse et régulation d'atmosphère, etc.), il est de plus en plus requis de pouvoir ajouter, interchanger ou sinon épargner des dispositifs annexes au système d'essorage : c'est ainsi que les configurations à géométrie très statique présentées ci-dessus ne permettent pas ou de manière fort complexe de garantir une flexibilité suffisante d'ajout, d'interchanger ou de supprimer des dispositifs spé cifiques. Indeed, depending on the mechanical and chemical properties of the product to be coated, the coating used, the coating process and the coating quality tolerances to be guaranteed by specific measures (strip distance, coating thickness, coating composition , temperature, pressure, analysis and regulation of atmosphere, etc.), it is increasingly required to be able to add, interchange or otherwise spare devices annexed to the spinning system: this is how configurations with a very high geometry. statics presented above do not make it possible, or in a very complex manner, to guarantee sufficient flexibility in adding, interchanging or removing specific devices.
Enfin, il est à noter que les installations de revêtement précitées requièrent des étapes de maintenance spécifiques pour chacune de leurs composantes (système d'essorage, dispo sitifs de stabilisation, capteurs de mesure...). En raison de leur configuration intégrée, il est alors nécessaire de reti rer la totalité de l'installation de part et d'autre de la bande, par exemple au moyen d'un pont de levage afin de la déplacer hors de la surface du bain. Ce type de manœuvre est ainsi très contraignant si l'opération de maintenance est mi neure (changement ou ajout de capteur par exemple), car il signifie un arrêt fort coûteux de production de produit revê tu. Finally, it should be noted that the aforementioned coating installations require specific maintenance steps for each of their components (dewatering system, stabilization devices, measurement sensors, etc.). Due to their integrated configuration, it is then necessary to remove the entire installation on either side of the belt, for example by means of a lifting bridge in order to move it away from the surface of the bath. . This type of maneuver is therefore very restrictive if the maintenance operation is minor (changing or adding a sensor for example), because it means a very costly stoppage of the production of the coated product.
Un but de la présente invention est de proposer une installa tion de revêtement de produit métallique en défilement munie d'au moins un système d'essorage et d'au moins un dispositif annexe permettant de résoudre les problèmes précités, en par ticulier de favoriser une reconfiguration géométrique modu laire et une maintenance simple du dit système d'essorage et de dispositifs annexes. An object of the present invention is to provide an installation for coating a moving metal product provided with at least one dewatering system and at least one ancillary device making it possible to solve the aforementioned problems, in particular to promote a modular geometric reconfiguration and simple maintenance of said wiping system and related devices.
Il est ainsi proposé une installation de revêtement de pro duit métallique en défilement de type bande au travers des caractéristiques de la revendication 1. There is thus proposed an installation for coating a moving metal product of the strip type through the features of claim 1.
A partir d'une installation de revêtement de produit métal lique en défilement longitudinal de type bande, comprenant : From a strip type longitudinal scrolling metal product coating installation, comprising:
- Un bac contenant ledit revêtement sous forme liquide dans lequel est plongé le produit métallique ;- A tank containing said coating in liquid form in which the metallic product is immersed;
- Un système d'essorage disposé en sortie verticale du produit hors du dit bac et dédié à essorer chaque face du produit de type bande, - A squeezing system arranged at the vertical outlet of the product outside the said tank and dedicated to squeezing each side of the strip-type product,
- Au moins un dispositif annexe au dit système d'essorage (par exemple un dispositif de stabilisa tion électromagnétique de bande) disposé en sortie du produit hors du système d'essorage et en vis-à-vis d'au moins une des faces du produit ; - At least one device annexed to said wiping system (for example an electromagnetic strip stabilization device) disposed at the outlet of the product outside the wiping system and facing at least one of the faces of the product ;
- Un moyen de maintien maintenant le système d'essorage et le dispositif annexe au-dessus du bac ; - A means of maintaining the wiping system and the ancillary device above the tank;
L'invention prévoit que le moyen de maintien comprend une unité de solidarisation formant un maintien latéral commun pour le système d'essorage et chaque dispositif annexe au moyen de multiples points de solidarisation. Il est ici entendu que chaque dispositif annexe comprend au moins une des composantes suivantes : The invention provides that the holding means comprises an attachment unit forming a common lateral support for the wiping system and each ancillary device by means of multiple attachment points. It is understood here that each ancillary device comprises at least one of the following components:
- un dispositif de stabilisation de bande ; - a tape stabilization device;
- un dispositif de mesure telle qu'une jauqe à chaud, un cap teur de distance ou une série mono- ou bidimensionnelle de tels capteurs ; a measuring device such as a hot dipstick, a distance sensor or a one-dimensional or two-dimensional series of such sensors;
- un dispositif de contrôle de qualité de revêtement (con trôle de fleuraqe par exemple) ; - a coating quality control system (flower control for example);
- Un dispositif de contrôle de refroidissement, par exemple sous forme d'une boite de confinement à atmosphère contrô lée ; - A cooling control device, for example in the form of a controlled atmosphere containment box;
- un dispositif d'aspersion pour minimiser le fleuraqe, par exemple au moyen d'une aspersion de poudre d'alumine pour un revêtement de type AZ « Aluminium-Zinc » ou AS « Aluminium- Silicium ». a sprinkling device to minimize the flow, for example by means of a sprinkling of alumina powder for a coating of the AZ “Aluminum-Zinc” or AS “Aluminum-Silicon” type.
Ainsi, un montaqe, un démontaqe, un échanqe d'un de ces dis positifs annexes (ou du système d'essoraqe) peut être avanta geusement effectué en désolidarisant uniquement le ou les points de solidarisation dédié(s) au dit dispositif annexe (ou au système d'essoraqe). Il en ressort ainsi d'une part que la maintenance de l'installation selon l'invention est simplifiée, puisque toute l'installation de revêtement (hors bac) ne doit plus être complètement retirée par un pont de levaqe, mais peut être réalisée sélectivement par un chariot élévateur au sol venant arrimer un dispositif annexe (ou le système d'essoraqe) au niveau de ses points de solidarisation pour le retirer, le replacer ou le remplacer dans l'unité de solidarisation formant un maintien latéral commun. D'autre part, en fonction du nombre de points multiples de solidari sation disposé sur l'unité de solidarisation, il est possible d'ajouter des dispositifs annexes complémentaires en fonction des besoins requis pour optimiser le processus de revêtement. Ainsi, la configuration géométrique de l'installation de re vêtement peut aisément être rendue modulaire. Thus, an assembly, a dismantling, an exchange of one of these ancillary devices (or of the scouring system) can be advantageously carried out by disconnecting only the attachment point (s) dedicated to said ancillary device (or to the dewatering system). It thus emerges from this on the one hand that the maintenance of the installation according to the invention is simplified, since the entire coating installation (excluding the tank) no longer has to be completely removed by a lifting bridge, but can be carried out selectively. by a forklift on the ground coming to secure an ancillary device (or the wringing system) at its securing points in order to remove it, replace it or replace it in the securing unit forming a common lateral support. On the other hand, depending on the number of multiple attachment points arranged on the attachment unit, it is possible to add additional ancillary devices as a function of of the needs required to optimize the coating process. Thus, the geometric configuration of the re-garment installation can easily be made modular.
Cette maintenance simplifiée et cette modularité accrue peu vent ainsi être optimisées en prévoyant que les points de so- lidarisation comprennent un moyen d'ancrage amovible entre l'unité de solidarisation et chaque dispositif annexe ou le système d'essorage. Enfin, ces moyens d'ancrage assurent un maintien latéral suffisant (et ainsi non surdimensionné pour des raisons de coûts et de compacité) de chaque dispositif annexe et du système d'essorage, par exemple en prévoyant les dits ancrages de type mâle/femelle ou de type support par ap pui ou par suspension adapté à maintenir chacun des disposi tifs annexes ou du système d'essorage. This simplified maintenance and this increased modularity can thus be optimized by providing that the securing points include a removable anchoring means between the securing unit and each ancillary device or the wiping system. Finally, these anchoring means provide sufficient lateral support (and thus not oversized for reasons of cost and compactness) of each ancillary device and of the wiping system, for example by providing said anchors of the male / female type or of the support type by support or by suspension adapted to hold each of the ancillary devices or of the wiping system.
Enfin, les points de solidarisation sont prévus mobiles dans l'unité de solidarisation et peuvent ainsi présenter avanta geusement les caractéristiques suivantes : Finally, the attachment points are provided to move in the attachment unit and can thus advantageously have the following characteristics:
- Les points de solidarisation sont indépendamment mo biles verticalement : ceci permet d'une part de dis poser chaque dispositif annexe ou le système d'essorage à une distance souhaitée au-dessus du bac et d'autre part, il est possible de disposer chaque dispositif annexe ou le système d'essorage à des hau teurs relatives variables. Ces deux aspects fort avantageux ont pour conséquences que les processus de revêtement en fonction des produits à revêtir peuvent être modifiés dynamiquement en reconfigurant la géo métrie des dispositifs annexes utiles au revêtement, en particulier à bonne hauteur du bac pour obtenir un effet technique optimal. - Les points de solidarisation prévoient des transla teurs ou/et des pivots mobiles de type 2D ou 3D, de sorte que des dispositifs annexes ou/et le système d'essorage puissent être dynamiquement réalignés sur un format ou un positionnement horizontal variable de la bande en défilement vertical. Enfin, l'unité de solidarisation peut aussi être mobile transversale ment par rapport au bac afin de compenser des déca lages de largeurs de bandes soudées se succédant en défilement continu à la sortie du bac. - The attachment points are independently movable vertically: this makes it possible, on the one hand, to position each ancillary device or the spinning system at a desired distance above the tank and, on the other hand, it is possible to arrange each ancillary device or the wiping system at varying relative heights. These two very advantageous aspects have the consequence that the coating processes depending on the products to be coated can be dynamically modified by reconfiguring the geometry of the ancillary devices useful for the coating, in particular at the right height of the tank to obtain an optimal technical effect. - The attachment points provide for conveyors or / and mobile pivots of 2D or 3D type, so that ancillary devices or / and the spinning system can be dynamically realigned on a variable format or horizontal positioning of the strip in vertical scrolling. Finally, the securing unit can also be movable transversely with respect to the tank in order to compensate for shifts in widths of welded strips which follow one another in continuous movement at the outlet of the tank.
A cet effet, l'installation selon l'invention peut ainsi com prendre une régulation de positionnement des points de soli darisation à mobilité contrôlée, ladite régulation étant ré gie par un opérateur ou un automate émettant des signaux de commande d'au moins un dispositif annexe de mesure (capteur de distance, jauge dite à chaud, tiède ou à froid, etc.) vers une unité de déplacement des dits points de solidarisation. To this end, the installation according to the invention can thus comprise a regulation of the positioning of the soli darisation points with controlled mobility, said regulation being regulated by an operator or an automaton transmitting control signals of at least one device. measurement annex (distance sensor, so-called hot, lukewarm or cold gauge, etc.) to a unit for moving said attachment points.
Idéalement pour garantir les avantages précités, l'installation selon l'invention prévoit que l'unité de soli darisation comprend deux éléments latéraux de soutien du sys tème d'essorage et d'au moins un dispositif annexe, chacun des dits éléments latéraux présentant les multiples points de solidarisation latéraux étant couplés à au moins deux extré mités latérales du système d'essorage et de chaque dispositif annexe. Ideally in order to guarantee the aforementioned advantages, the installation according to the invention provides that the soli darisation unit comprises two lateral support elements for the wiping system and at least one ancillary device, each of said lateral elements having the elements. multiple lateral attachment points being coupled to at least two lateral ends of the wiping system and of each ancillary device.
Un ensemble de sous-revendications présente également des avantages de l'invention. A set of sub-claims also presents advantages of the invention.

Figure 1 et 2 présentent respectivement une vue de côté (plan X, Z) et une vue de face (Y, Z) d'un exemple de réalisation de l'installation de revêtement de produit métallique (1) en défilement de type bande selon l'invention. Figure 1 and 2 show respectively a side view (X, Z plane) and a front view (Y, Z) of an exemplary embodiment of the installation for coating a metal product (1) in tape type scrolling according to invention.
Comme connu dans l'état de la technique, le revêtement est prévu dans un bac (B) formant un bain de revêtement sous forme de métal liquide par exemple constitué de zinc, de ma gnésium, d'aluminium ou autres éléments pour former des al liages spécifiques. Le produit métallique de type bande en défilement est alors plongé dans le dit bain au niveau de sa surface (S) de métal liquide, passe sur un rouleau de fondAs known in the state of the art, the coating is provided in a tank (B) forming a coating bath in the form of liquid metal, for example consisting of zinc, magnesium, aluminum or other elements to form al. specific bindings. The metal product of the scrolling strip type is then immersed in said bath at the level of its surface (S) of liquid metal, passes over a bottom roller
(2) dans le bain puis passe entre des rouleaux correcteurs(2) in the bath then pass between correcting rollers
(3) afin de ressortir du bain généralement verticalement (= direction longitudinale Z) à la surface du bain afin de tran siter dans un système d'essorage (4) disposé à une première hauteur de la surface haute du revêtement liquide dans le bac (h4) - c'est-à-dire en sortie du produit hors du dit bac - et dédié à essorer chaque face du produit de type bande, par exemple sous forme de deux lames d'air disposées transversa lement (= direction horizontale Y) de part et d'autre de la bande en vis-à-vis de chacune de ses faces. Dans le cas des figures 1 et 2, une traverse (T) de maintien du système d'essorage est disposée en partie supérieure de l'installation de revêtement. Cette traverse se compose ici de deux poutres disposées chacune au-dessus de chacune des deux lames d'air afin de les maintenir à une distance hori zontale souhaitée de la bande lors de l'essorage. Ces poutres sont solidarisées à la périphérie du bac par exemple au moyen de piliers latéraux au bac (Tl, T2). (3) in order to emerge from the bath generally vertically (= longitudinal direction Z) at the surface of the bath in order to pass through a dewatering system (4) arranged at a first height of the upper surface of the liquid coating in the tank ( h4) - that is to say at the outlet of the product outside the said tank - and dedicated to wringing each side of the strip-type product, for example in the form of two air knives arranged transversely (= horizontal direction Y) on either side of the strip facing each of its faces. In the case of Figures 1 and 2, a cross member (T) for maintaining the wiping system is arranged in the upper part of the coating installation. This crosspiece here consists of two beams each arranged above each of the two air knives in order to keep them at a desired horizontal distance from the strip during the dewatering. These beams are secured to the periphery of the tank for example by means of side pillars to the tank (T1, T2).
Selon ce mode de réalisation, l'installation de revêtement de produit métallique (1) en défilement longitudinal (Z) de type bande selon l'invention comprend ainsi : According to this embodiment, the installation for coating a metallic product (1) in longitudinal movement (Z) of the strip type according to the invention thus comprises:
- Un bac (B) contenant ledit revêtement sous forme de métal liquide dans lequel est plongé le produit mé tallique ; - A tank (B) containing said coating in the form of liquid metal in which the metallic product is immersed;
- Un système d'essorage (4) disposé en sortie verticale (= direction longitudinale Z) du produit hors du dit bac et dédié à essorer chaque face du produit de type bande, - A squeezing system (4) arranged at the vertical outlet (= longitudinal direction Z) of the product outside said tank and dedicated to squeezing each side of the strip-type product,
- Au moins un dispositif annexe (5) disposé en sortie du produit hors du système d'essorage et en vis-à-vis d'au moins une des faces du produit ; - Un moyen de maintien (6, T) maintenant le système d'essorage et le dispositif annexe ; - At least one ancillary device (5) disposed at the outlet of the product outside the dewatering system and facing at least one of the faces of the product; - A holding means (6, T) holding the spinning system and the ancillary device;
- le moyen de maintien comprenant une unité de solidari- sation (6) formant un maintien latéral commun pour le système d'essorage et chaque dispositif annexe au moyen de multiples points de solidarisation (64, 65). - the holding means comprising an attachment unit (6) forming a common lateral support for the wiping system and each ancillary device by means of multiple attachment points (64, 65).
Le dispositif annexe (5) est ici disposé au-dessus du système d'essorage (4) à une deuxième hauteur (h5) de la surface (S) du bain de métal liquide dans le bac. Comme précédemment ex pliqué, les points de solidarisation (64, 65) peuvent être prévus mobiles, de sorte que la première et la deuxième hau teur (h4, h5) peuvent être flexiblement et indépendamment mo difiés, en fonction des paramètres requis par le processus de revêtement, du type de revêtement et du produit à revêtir.The ancillary device (5) is here arranged above the wiping system (4) at a second height (h5) from the surface (S) of the bath of liquid metal in the tank. As previously explained, the attachment points (64, 65) can be provided movable, so that the first and second height (h4, h5) can be flexibly and independently changed, depending on the parameters required by the process. coating, type of coating and product to be coated.
Des pivots - ici à axes horizontaux - peuvent aussi être pré vus afin par exemple de varier une orientation du point ver tical de soufflage depuis le système d'essorage vers la bande en défilement vertical. Aux mêmes fins d'optimisation du fonctionnement de l'installation selon l'invention, de tels moyens de pivots 2D ou 3D peuvent aussi être prévus, de ma nière à garantir des degrés de liberté du système d'essorage (par exemple pour une correction d'inclinaison horizontale selon un profil de bande incliné) mais aussi des dispositifs annexes (par exemple pour une correction d'inclinaison du point de mesure visée sur une bande). Pivots - here with horizontal axes - can also be provided in order for example to vary an orientation of the vertical blowing point from the dewatering system towards the vertically moving strip. For the same purposes of optimizing the operation of the installation according to the invention, such 2D or 3D pivot means can also be provided, so as to guarantee the degrees of freedom of the wiping system (for example for a correction horizontal inclination according to an inclined strip profile) but also ancillary devices (for example for an inclination correction of the measuring point aimed at on a strip).
Pour l'exemple de l'installation selon figure 1 ou 2 (et des autres figures décrites 3-7 ci-après), l'unité de solidarisa tion (6) comprend plus spécifiquement deux éléments latéraux de soutien du système d'essorage (4) et du dispositif—annexe (5), chacun des dits éléments latéraux présentant les mul tiples points de solidarisation latéraux (64, 65, 67, 68) étant couplés à au moins deux extrémités latérales du système d'essorage et de chaque dispositif annexe (5, 7, 8). For the example of the installation according to figure 1 or 2 (and the other figures described 3-7 below), the securing unit (6) more specifically comprises two lateral support elements for the wiping system ( 4) and of the device — annex (5), each of said lateral elements having the multiple lateral attachment points (64, 65, 67, 68) being coupled to at least two lateral ends of the wiping system and of each ancillary device (5, 7, 8).
Puisque le système d'essorage est le premier équipement en sortie de bande du bac, il est aussi possible de prévoir deux points de solidarisation (64) formés par un ancrage en sus pension dudit système d'essorage au-dessous de chacun des éléments latéraux (6) de part et d'autre de la bande. Since the wiping system is the first item of equipment at the end of the strip from the bin, it is also possible to provide two securing points (64) formed by an anchoring in suspension of said wiping system below each of the side elements. (6) on either side of the strip.
Dans l'exemple de l'installation selon figure 1 ou 2, le moyen de maintien comprend simplement une traverse (T) hori zontale maintenant l'unité de solidarisation formée par ses deux éléments latéraux (6) de soutien du système d'essorage (4) et du dispositif—annexe (5). La traverse (T) est ici sou tenue au-dessus du bac par deux supports latéraux sous forme de piliers latéraux (Tl, T2) au bac. Les supports latéraux peuvent comprendre des moyens d'élévation de la traverse, mais ceux-ci requièrent une motorisation plus puissante et coûteuse que plusieurs motorisations dédiées à chaque posi tionnement de certains points de solidarisation (64, 65).In the example of the installation according to FIG. 1 or 2, the holding means simply comprises a horizontal cross member (T) maintaining the securing unit formed by its two lateral elements (6) for supporting the wiping system ( 4) and the device — annex (5). The crosspiece (T) is here held above the tray by two side supports in the form of side pillars (Tl, T2) to the tray. The side supports can include means for elevating the cross member, but these require a more powerful and expensive motorization than several dedicated motors for each position of certain attachment points (64, 65).
Pour une maintenance complète du système d'essorage et du dispositif annexe, il est possible de venir désolidariser la traverse de ses piliers latéraux (Tl, T2) puis de la retirer avec un pont de levage. Toutefois, si une maintenance plus spécifique est uniquement requise sur un module comme le sys tème d'essorage (4) ou un des dispositifs annexes (5), il est avantageusement possible de venir déverrouiller des ancrages amovibles aux points de solidarisation dudit module à mainte nir et de retirer le dit module sans démonter la traverse et les équipements restants. Un tel retrait peut idéalement si faire par un simple chariot élévateur, au lieu d'un pont de levage. Figure 3 présente une première option de l'installation de revêtement selon figure 2, en vue de face, en ce qu'elle com prend un support de guidage (T0, R) disposé latéralement au bac (B), et à l'unité de solidarisation (6) en position de travail au-dessus dudit bac, afin de pouvoir escamoter hori zontalement hors de la zone du bac ladite unité de solidari sation (6) et les équipements attenants de système d'essorage et de dispositif annexe (4, 5). A titre d'exemple, le support de guidage comprend fort simplement un pilier de support (T0) maintenant un rail (R) horizontal et couplé à un pilier laté ral (Tl), le dit rail étant disposé à une hauteur dédiée à assurer une coulisse de l'unité de solidarisation (6) mainte nant les équipements attenants de système d'essorage et de dispositif annexe (4, 5) depuis sa position sous la traverse (T) vers une position de parking hors de la zone du bac (B). Ainsi, une maintenance des équipements peut aussi être réali sée sans danger pour un opérateur et sans moyen de levage complexe. For complete maintenance of the wiping system and of the ancillary device, it is possible to separate the cross member from its side pillars (T1, T2) and then to remove it with a lifting bridge. However, if more specific maintenance is only required on a module such as the spinning system (4) or one of the ancillary devices (5), it is advantageously possible to unlock removable anchors at the points of attachment of said mainte module. nish and remove said module without dismantling the cross member and the remaining equipment. Such removal can ideally if done by a simple forklift, instead of a lifting bridge. Figure 3 shows a first option of the coating installation according to Figure 2, in front view, in that it comprises a guide support (T0, R) arranged laterally to the tank (B), and to the unit of securing (6) in the working position above said tray, in order to be able to retract horizontally out of the area of the tray said securing unit (6) and the adjoining equipment for the wiping system and ancillary device (4 , 5). By way of example, the guide support very simply comprises a support pillar (T0) maintaining a horizontal rail (R) and coupled to a lateral pillar (Tl), said rail being arranged at a height dedicated to ensuring a slide of the securing unit (6) maintaining the adjoining equipment for the spinning system and ancillary device (4, 5) from its position under the cross member (T) to a parking position outside the bin area ( B). Thus, equipment maintenance can also be carried out without danger for an operator and without complex lifting means.
Figure 4 présente une deuxième option de l'installation de revêtement selon figures 2 et 3, en vue de face, en ce que l'installation selon l'invention prévoit que l'unité de soli darisation (6', 6'') - ici sous la même forme que les élé ments latéraux (6) des figures 1 et 2 - est soutenue au- dessus du bac par au moins un support latéral (T', T'') au bac et posé au sol (G), soit à minima d'un côté du bac, soit idéalement de part et d'autre du bac au moyen des deux sup ports latéraux (T', T'') comme représentés ici. Ce type de supports latéraux permet d'épargner une traverse relativement massive comme la traverse (T) aux figures 1 et 2 ou du moins de prévoir une ou deux telles traverses (T''', T'''') moins massives reliées aux parties supérieures ou/et inférieures des éléments latéraux (6', 6'') pour rigidifier l'unité de solidarisation (6', 6''), car en mode de fonctionnement de l'installation de revêtement, les éléments latéraux solidari sant le système d'essorage (4) et chaque dispositif annexe (5) sont stablement calés entre les deux supports latérauxFigure 4 shows a second option of the coating installation according to Figures 2 and 3, in front view, in that the installation according to the invention provides that the solidification unit (6 ', 6'') - here in the same form as the side elements (6) of Figures 1 and 2 - is supported above the tank by at least one side support (T ', T'') to the tank and placed on the ground (G), either at least on one side of the tank, or ideally on either side of the tank by means of the two lateral supports (T ', T'') as shown here. This type of lateral support makes it possible to save a relatively massive cross member such as the cross member (T) in Figures 1 and 2 or at least to provide one or two such less massive cross members (T ''',T'''') connected to the upper or / and lower parts of the side elements (6 ', 6'') to stiffen the unit of securing (6 ', 6''), because in the operating mode of the coating installation, the side elements securing the wiping system (4) and each ancillary device (5) are stably wedged between the two side supports
(T', T" ). (T ', T ").
Un autre avantage de cette installation selon figure 4 réside en ce que l'unité de solidarisation (6', 6'') peut être prévu escamotable latéralement au bac, idéalement au moyen d'au moins un des support latéraux (T', T'') prévu (s) mobile(s) latéralement au bac. Le support latéral mobile (T') peut par exemple comprendre un pivot horizontal ou bien, alternative ment un moyen de translation au sol comme représenté en fi gure 4. Ici, en figure 4, en partie droite, l'installation de revêtement en mode de fonctionnement actif de revêtement est représentée, les éléments latéraux (6', 6'') solidarisant le système d'essorage (4) et chaque dispositif annexe (5) étant stablement calés entre les deux supports latéraux (T', T''). En partie gauche de la figure 4 et en pointillé, l'installation de revêtement en mode de maintenance est re présentée, les éléments latéraux (6', 6'') solidarisant le système d'essorage (4) et chaque dispositif annexe (5) ayant été décalés au sol (G) au moyen du support latéral (T') ini tialement disposé au voisinage et à gauche du bac. Ici en core, il est ainsi facile de venir retirer l'installation de revêtement (hors bac) ou d'un de ses modules (4, 5) au moyen d'un simple chariot élévateur pour l'emmener dans une zone de maintenance. Another advantage of this installation according to FIG. 4 lies in that the securing unit (6 ', 6' ') can be provided for retracting laterally to the tank, ideally by means of at least one of the lateral supports (T', T '') provided mobile (s) laterally to the tank. The mobile lateral support (T ') can for example comprise a horizontal pivot or alternatively a means of translation on the ground as shown in FIG. 4. Here, in FIG. 4, in the right part, the coating installation in mode. active coating operation is shown, the side elements (6 ', 6' ') securing the wiper system (4) and each annex device (5) being stably wedged between the two side supports (T', T '' ). In the left part of Figure 4 and in dotted lines, the coating installation in maintenance mode is shown, the side elements (6 ', 6' ') securing the wiping system (4) and each ancillary device (5 ) having been offset on the ground (G) by means of the lateral support (T ') initially placed in the vicinity and to the left of the tank. Here again, it is thus easy to come and remove the coating installation (excluding the tank) or one of its modules (4, 5) by means of a simple forklift to take it to a maintenance area.
Figure 5 présente une troisième option de l'installation de revêtement selon une des figures 2 à 4, en vue de face, en ce que l'installation selon l'invention prévoit que le moyen de maintien (6', 6'') - ici sous la même forme que les deux élé- ments latéraux (6) des figures 1 et 2 d'un côté de la bande - est soutenu au-dessus du bac par au moins un support latéral (T', T'') au bac, ici chacun des deux dits supports latéraux (T', T'') étant eux-mêmes couplés par une traverse (T) selon figure 2 afin de rendre le moyen de maintien plus rigide (pour un maintien anti-vibrations) sur toute la largeur du bac ou au moins de la bande. En ce sens, la traverse (T) (ou les deux poutres de chaque côté des faces de bande) et au moins les deux supports latéraux (T', T'') peuvent aussi idéalement former un ensemble monobloc. Chacun des éléments latéraux du moyen de maintien (6', 6'') est fixé latéralement à chacun des supports latéraux (T', T'') de manière ainsi aussi très robuste. Figure 5 shows a third option of the coating installation according to one of Figures 2 to 4, in front view, in that the installation according to the invention provides that the holding means (6 ', 6'') - here in the same form as the two elements side elements (6) of Figures 1 and 2 on one side of the strip - is supported above the tank by at least one side support (T ', T'') to the tank, here each of the two said side supports ( T ', T'') being themselves coupled by a cross member (T) according to Figure 2 in order to make the holding means more rigid (for anti-vibration hold) over the entire width of the tank or at least of the strip . In this sense, the cross member (T) (or the two beams on each side of the strip faces) and at least the two lateral supports (T ', T'') can also ideally form a single unit. Each of the lateral elements of the retaining means (6 ', 6'') is fixed laterally to each of the lateral supports (T', T '') thus also very robust.
Enfin, les dits supports latéraux (T', T'') ou l'ensemble mo nobloc sont maintenus par des piliers latéraux (Tl, T2) dis posé au voisinage du bac tels qu'en figure 2, ce maintien pouvant être mobile transversalement par rapport au bac afin de compenser des décalages de largeurs de bandes soudées se succédant en défilement continu à la sortie du bac. Finally, said side supports (T ', T' ') or the mo nobloc assembly are held by side pillars (Tl, T2) placed in the vicinity of the tank such as in Figure 2, this support can be movable transversely in relation to the tank in order to compensate for offsets in the widths of welded strips which follow one another in continuous movement at the exit of the tank.
Figure 6 et 7 présentent respectivement une quatrième et une cinquième options de l'installation de revêtement selon une des figures 2 à 5 (et 6 pour la figure 7), en vue de face, afin de mieux montrer l'aspect avantageux d'une modularité accrue et flexible de l'installation de revêtement selon l'invention. En effet, comme précédemment décrit, les élé ments latéraux (6, 6', 6'') forment des supports latéraux au système d'essorage (4) et à un ou plusieurs dispositifs an nexes (5, 7, 8) en prévoyant simplement un nombre (= le double) de points de solidarisations dédiés à chacun de ces modules (4, 5, 7, 8).
